I just picked this up from a local estate. I thought it was ivory until I removed it from its frame to discover it is carved cameo shell portrait of Pope Pius XI (1792-1878). It is most likely mid to late 19th century, certainly Victorian. The attention to detail is amazing as you can see and I held it up to a light at different angles to get a look. It is nearly 1 3/4" tall and about 1 3/8" wide. In excellent condition with no damages. The frame is probably 30 years old or so and measures about 7 1/8 x 7 1/2".
